8 Best Eyelash Growth Serums

Use this serum on both your upper and lower lashes to hydrate existing lashes. The mix of vitamins and active botanicals support the natural lash cycle, helping them look healthier and fuller. “The fine tip is great for precise application so that product doesn’t run into eyes and is not wasted in the process,” says Aral.

This nourishing product uses ingredients that are 100% plant-derived and/or organic — such as aloe and castor oil — which help to nurture and enhance existing lashes. Even more: you can use this eyelash serum even if you have extensions.
